An important feature of depression for this book is its link to social relationships. People are more likely to become depressed when they become (or feel) more socially disconnected, and depression then makes people less interested and able to seek out social connection. As with anxiety, there is a vicious circle. So I’ll be paying close attention to friendship and social relationships in this book. We’ll see that a play-based childhood strengthens them, while a phone-based childhood weakens them.
